Well return and print are entirely two different processes. If it's designed to print, there's usually no point in returning a value, and if it's designed to return a value, there's usually no point in printing since the caller can print it if it wants. It goes back to the concept of what the function is designed to do. In general, this sort of thing is rarely done in programming. If you need the function to both print and return a value, it's perfectly acceptable. There is no significant impact on the program other than the fact you end up printing a lot of stuff that may not need to be printed.

Same function and its possible impact on a program. Return but rather if it is considered good style to use both in the So the highlight of the question isnt the difference between print and The function (or person) that calls the function can then decide to print it, write it to a file, pass it to another function, etc. In all other cases, a function should return a value.

It's relatively rare to use both, except during a debugging phase where the print statements help see what's going on if you don't use a debugger.Īs a rule of thumb I think it's good to avoid adding print statement in functions, unless the explicit purpose of the function is to print something out. If you need the result for further calculation, use return. If you indeed just want to print a result, use print. They appear to do the same thing when running trivial examples interactively, but they are completely different. Print and return solve two completely different problems. Would the result be two c's? Assume c = 5 therefore, would the output be(?): 5 So the highlight of the question isn't the difference between print and return, but rather if it is considered a good style to use both in the same function and if it has a possible impact on a program. Is it advisable to use the print statement in the function to display output rather than placing a return statement at the end and using the print(function(a))?Īlso what implications would there be if I used both a print statement and a return statement in a function to display the same output? Lets imagine I need to show the answer for c and then use the value of c somewhere else. Lets say I have the function: def function(a)
